Is there a size limit to the size of expansion card that the Cali will accept?

you can only use as much as the motherboard are made for.

no, i'm sorry the maximum amount of ram the motherboard will recognize is 512 mb, it's not an OS limit it's a MOBO limit

Probably the first thing to try is formatting the card. There should be a function in the setup menus to do this. If it won't format or gives an error when you try the card may be incompatible. SD and SDHC cards fit the same slots, but many cameras won't work with the SDHC (high capacity) cards. Some cameras have a capacity limit, and won't work with cards that are too large (in memory terms).

Hi,

Take the stick of 512 out of the motherboard and insert the 1GB stick in DIMM 1 slot and switch the machine on. If it comes on check whether it has registered it as 1GB. If it has turn the machine off and just put in the 512 stick.

If the machine won't boot up with the 1GB stick then it could be faulty or the motherboard doesn't support 400MHz (which it should).


Regards.

According to Hp website your computer will handle two 512 Mb RAM chips. Make sure they are PC133. If computer will not boot with both inserted properly, one of them is bad. Put one in slot 1 and none in slot 2 and see if it boots. Then switch the chips put the extra chip in slot 1 and none in slot 2. See if it boots. This way you can troubleshoot a possible bad chip.

You can do this in two ways: opening your notebook and taking a look on the memory modules already installed (we will explain more about this later) or running a program like Everest (available on our download section). We ran Everest (going to Motherboard, Chipset, Memory Slots) on our notebook and found that it was using two 256 MB DDR-SDRAM PC2700 (“DDR333”) modules, for a total of 512 MB.

Figure 1: Checking your current memory configuration with Everest.
If your notebook has an empty memory slot, just go to the computer store and buy a new SO-DIMM module with the same technology (SDRAM or DDR-SDRAM) and speed of any capacity you want – of course you need to know the capacity limit of your notebook. You cannot install a 1 GB module in a notebook that only accepts modules up to 512 MB, for example. Our notebook – a Sony Vaio PCG-V505ECP – accepts modules up to 1 GB, for a total of 2 GB RAM, since it has two memory slots.
For example, if your notebook has one 256 MB module and an empty memory slot, if you buy and install another 256 MB module, it will have 512 MB RAM. If you buy and install a 512 MB module, your notebook will have 768 MB.
If your notebook already has two memory modules, you will need to remove one of the installed modules in order to install the new one. If the two modules have the same capacity, it doesn’t matter which one you will take away, but if they have different capacities, remove the one with smaller capacity. The new RAM capacity of your notebook will be of the capacity of the remaining module plus the capacity of the new module.
In our case, our notebook has two 256 MB modules. So we will remove one of these modules and install a new one on its place. We bought a 1 GB-module, so after installing it our notebook will have 1,280 MB RAM installed (memory math is tricky, since 1 GB equals to 1,024 MB not 1,000; so 1,024 MB + 256 MB = 1,280 MB).

Are you sure its the correct speed/type of RAM? According to Google your laptop takes PC2700 DDR RAM, ensure you are using this in both slots to avoid problems. If you have it fully inserted into the slot and nothing happens when you swtich it on then the laptop doesnt like that type of RAM and you'll need to change it.

Hello,
Most likely your MB is too old for this upgrade although there is a chance you could flash your bios (reprogram your computer's brain to accept the new memory providing hp has a flash for it).
here is a link for the latest bios flash for your computer, use at your own risk.

good luck.

the memory is dual channel, so you have to use matched memory for it to work 1gig in each slot if possible, check the 1 gigs and 512's to see if they run at the same bus speed, if they are not matched there is your problem try a gig and a 512 in slot 0 to see if it picks the memory up, also there is sometimes an option in the bios to dissable dual mode
